A metallic element M reacts with oxygen to form an oxide with the formula M₂O₃. The formula of the corresponding chloride of the metal will be:

a. MCl₃
b. M₂Cl
c. MCl₂
d. M₂Cl₂



Answer :

183so2

Answer:

The correct answer is a. MCl₃.

Explanation:

1. The given information states that the metallic element M reacts with oxygen to form an oxide with the formula M₂O₃.

2. The corresponding chloride of the metal will have a similar chemical formula, where the chlorine atoms replace the oxygen atoms.

3. In the oxide M₂O₃, the metal M has an oxidation state of +3.

4. To maintain the same oxidation state in the chloride, the formula of the corresponding chloride will be MCl₃, where the metal M has an oxidation state of +3 and is bonded to three chlorine atoms.

Therefore, the correct answer is a. MCl₃.
